| ▶ Product Development Design |
|
Design drawings according to the product or
drawing requested by the customer. | |
|
| ▶ Mold making |
|
A mold for injection of the wax pattern is manufactured in
consideration of the expected order quantity and the like in
accordance with the prepared drawings. | |
|
| ▶ Wax pattern production |
|
injecting a semi-solid wax into the mold to
mold the solid wax circle. | |
|
| ▶ Wax assembly |
|
A wax pattern projected by a mold is a step of making
a tree (mold) by assembling in the form of a twig into
a runner bath produced in advance. | |
|
| ▶ Coating(Molding) |
|
It is a very important process to repeatedly apply the
assembled mold with special ceramics material several times
and it is a molding operation that takes a long time. This
process is one of the important processes that determine
the quality of precision castings. | |
|
| ▶ De waxing |
|
It is the process of removing the wax circle inside by
dissolving the wax in the coated cell. | |
|
| ▶ Cell firing |
|
Before injecting the molten material into the cell,
the wax remaining in the cell is completely removed,
and the cell is placed in a firing furnace and sintered
/ preheated to improve the strength and air permeability
of the cell. | |
|
| ▶ Casting |
|
It is a process of injecting dissolved molten material into
a cell (mold), and it can be said that it is a process in
which the shape of a product requested by a customer is
produced. | |
|
| ▶ Absorption(cell removal) |
|
When the mold is completely cooled, it is not necessary to
use a ceramic mold attached to the mold surface of the
tree-like mold, so that it is a process of separating by
using a physical impact such as a hammer. | |
|
| ▶ Excision |
|
Cutting various cutting equipment at the gate part of the
product attached at regular intervals at regular intervals
and performing the separation process. | |
|
| ▶ Grinding |
|
This is the process of grinding / mapping the
residual gate, which is the injection port of the product,
through the sandbelt. | |
|
| ▶ Short and post processing |
|
Air shot, etc. Removal of sand buried in the casting process
After the series of finishing operations such as surface
modification, deformation correction, surface treatment,
etc. of the casting surface improvement, the desired
precision casting with added value is completed. | |
|
| ▶ Heat treatment |
|
It is a heat treatment process to increase the mechanical
properties of the product. | |
|
| ▶ Calibration and Inspection |
|
It is a final inspection process that confirms whether
the finished finishing precision casting conforms to the
various quality levels required by the drawing, and
if it is necessary to calibrate it, it completes the
complementary work and confirms whether it is good or not. | |
|
| ▶ Packing and delivery |
|
The completed castings shall be packed and packed
according to the domestic packing export packing in
accordance with the customer's requirements. |
